Examples
Last month's P&L is a calendar month
On May 6 you sit down at your cafe to print April's results. In QuickBooks Online or Xero, set the report from April 1 to April 30. That date range is the April accounting period: the customary span for that income statement. An office client's $380 boxed-lunch invoice dated April 29 should appear in April sales. If you leave the dates on May 1–6, the days you are looking at the screen, April disappears and you are reading the next period.
A mid-month bank cut is not the period
Your plumbing shop's checking statement from the bank runs November 16 through December 15. You reconcile that window, then set the P&L to the same dates so cash and profit "match." That bank cycle is not the customary accounting period. Keep the operating statement on December 1–31 so the $1,850 backflow job you invoiced to a storage client on December 3 sits with December rent and payroll. Reconcile the bank to the statement; do not move the income statement to the bank's cut.
Why it matters
Every income statement covers a set span, usually a month, a quarter, or a year. That span is the accounting period, and you pick it every time you run a P&L or lock a month-end close. Run the report for the days you happen to be at the screen, or drop last month's sales and bills into the month you typed them, and that period's profit is wrong. This is not a ledger account, and it is not the same as a fiscal year, which is only a year that does not end in December.
